I’m horrible at riddles – however I can see where LSI spam would be a problem for cloaked/doorway pages and sites, but can’t figure out how it can be used for spamming in other ways.. unless they’re just chugging out spammy pages without even bothering to redirect to a more decent looking landing page.

re: “Clue: you’ll never be the first person in a new place if you only follow.”

Gah! Hmmm…Are they pumping out individual pages using a generator & database of states & city names along with their niche’s long tail keyword(s)..?

Or does their niche site have large, thorough sub-sections directly related to their website’s primary subject matter? (ie a carpet cleaning website also has a section all about vacuum cleaners, even though they aren’t in the business of actually selling the vacuum cleaners… just so the LSI aspect gives their entire site a boost in the SEs).. or am I giving away too much here? LOL
